Can you make cookies with icing instead of powdered sugar?
When making cookies, powdered sugar can be used instead of powdered sugar, because the two functions are similar, both of which are to increase sweetness, but powdered sugar can't replace corn starch, because when making cookies, corn starch will absorb water and keep its shape, while powdered sugar won't.
There are some differences between icing and powdered sugar. Sometimes powdered sugar can replace icing, but powdered sugar can be used as granulated sugar, but icing usually plays a decorative role. Frosting is obtained by processing powdered sugar, and is generally used as a dessert decoration.
If there is sugar at home, it can also be ground into powder instead of powdered sugar, which is better than frosting. In order to prevent caking, some starch is added to the icing, but other ingredients are basically the same as powdered sugar, so it will not have any effect when used to make cookies.
